To build Tianjin into a port and naval base, it is natural to build warships. Since the Spring and Autumn Period and the Warring States Period, most of the warships have been building ships.

The building ship is a kind of large warship with multi-storey buildings and offensive and defensive facilities, which looks like a building and is more than ten zhang high. Historically, Soochow once built a five-story ship that could carry more than 3,000 soldiers. In the battle on the water, the building ship can be described as both offensive and defensive, like a water fortress.

Of course, the defect of the building ship is also extremely obvious, that is, it is unsafe.

Building ships are mostly used in rivers and lakes, but also used in the near sea, due to the high center of gravity of the building ship, the poor ability to resist wind and waves is quite dangerous to use in the open sea. Almost all of the famous battles that Lou Chuan participated in were on the Yangtze River, such as the Battle of Chibi, the Battle of the Western Jin Dynasty to destroy Wu, the Battle of the Sui Dynasty to destroy Chen, and the Battle of the Yuan Dynasty to destroy the Southern Song Dynasty. Since the Song and Yuan dynasties, the use and records of building ships have gradually disappeared, and it is also because since the Sui and Tang dynasties, new warships have appeared, and building ships have withdrawn from the stage of history because of their own huge defects.

Yuan Chang wanted to realize the ideal of the Great Voyage, and naturally he couldn't do it with a building ship. At most, the building boat can come in handy on the Yangtze River, and even the Yellow River, which is a little turbulent, can't go down, let alone the more dangerous sea and ocean. Therefore, in order to realize the ideal of great navigation, it is indispensable to improve shipbuilding technology. After the Sui and Tang dynasties, the new type of warship was a vehicle ship, just like a bicycle, and the crew used a foot pedal to drive the warship, and its performance was undoubtedly much superior to that of the building ship. Of course, it is undoubtedly extremely difficult for vehicles and ships to enter the sea and the ocean. Therefore, after the building ships and chariots and ships were abandoned, only the iron ships powered by steam engines in later generations could sail on the sea and the ocean more safely.

As for guaranteeing 100% perfection, that's not possible. Even in the high-tech age of later generations, there were often dangerous situations on ships. Not to mention today's technology. The danger of the sea is unpredictable, and only those who have experienced that feeling can truly understand the danger of the sea.

And as for the construction of steam engines and tin boats. Although Yuan Chang is not in this industry, but. In my previous life, when I was in school, I finally had some understanding of the steam engine, and explained the principle to Ma Jun, thinking that with Ma Jun's invention ability, it should be possible to build a steam engine. There is also the problem that the tin boat will be eroded in the water, which is also easy to solve. That is steelmaking, smelting pig iron into steel, as long as there is enough temperature, it is not much of a problem. Today's coal mines are still very abundant. Open-pit mines can be seen everywhere, but the world does not know how to use them, with coal mines to solve the steel problem, and then Ma Jun to build a steam engine, Tianjin port and naval base construction, that is no problem at all.

Don't question the ability of the ancients, Huaxia was able to create four great inventions, which is an excellent proof. Just like Zhang Heng of the Eastern Han Dynasty, he was able to create a geokinetic instrument to sense the occurrence of earthquakes. Even in the afterlife, no one can make it, and that speaks for itself.

And when Yuan Chang was in his previous life, he saw a certain boat questioning Zhang Heng's geodynamic instrument on the Internet. It's just a thing that can only be seen and is useless. The reason why a certain boat has this statement is also because the ground motion instrument made by Zhang Heng has been lost in the war, and what appeared in front of the world at that time was a replica made according to Zhang Heng's theory. And it didn't work. Just think about it, there is a huge difference between the measurement of degrees in later generations and in today's era. It can be understood why the imitation geodynamic instrument of later generations will not work. In fact. The reason why a certain Zhouzi questioned Zhang Heng's geodynamic instrument, as far as Yuan Chang saw it, was just that this guy wanted to create public opinion to make a name for himself.

Yuan Chang looked at Ma Jun and asked, "Deheng, can you make the steam engine I told you about earlier?"

"Qi Yu Zhou Mu, the steam engine you mentioned is very exquisite, and it has not been able to be manufactured for a while. Now, I just have a little clue, but I have failed to live up to the high expectations of the state pastor. Ma Jun looked at Yuan Chang's expectant eyes, and lowered his head a little ashamedly, Yuan Chang had already told him the principle of the steam engine, but what he had made so far were all defective products, and they could not be put into use at all.

"Deheng, there is no need to rush in this matter. Maybe one day you have an inspiration, you can make it. Yuan Chang didn't mean to blame, and comforted Ma Jun with kind words.

In fact, in the Eastern Han Dynasty and the emperor's time, the ancient Greek mathematician Hero of Alexandria invented the world's first steam engine, of course, this is only the prototype of the steam engine; It wasn't until 1679 that the French physicist Denis Barpen built the first working model of a steam engine after observing steam escaping his pressure cooker. At about the same time, Samuel Moran also came up with the idea of a steam engine. Thomas Seville in 1698, Thomas Newcomen in 1712 and James Watt in 1769 built the early industrial steam engine, and they all contributed to the development of the steam engine. In 1807, Robert Fulton was the first to successfully use a steam engine to drive a steamer. Using scientific theories, Watt gradually discovered the problem with this steam engine. From 1765 to 1790, he made a series of inventions, such as a separate condenser, an insulation layer outside the cylinder, oil-lubricated pistons, planetary gears, parallel motion linkages, centrifugal governors, throttle valves, pressure gauges, etc., which increased the efficiency of the steam engine to more than three times that of the original Newcomen machine, and finally invented the steam engine in the modern sense.

In other words, from the prototype of the first steam engine to the appearance of the steam engine in the real sense, it has taken more than 1,600 years. However, Yuan Chang believed that with his theoretical guidance, Ma Jun, a strong inventor, would definitely be able to invent a perfect steam engine, of course, it was only a matter of time.

"Tian Kai, Xun Biao, Liu Shun, the construction of Tianjin will be entrusted to the three of you, I hope the three of you will not let the Benzhou Mu down. In addition, what Deheng creates is the top priority, and if Tianjin wants to build it thoroughly, what Deheng creates is also essential. Therefore, you must ensure the safety of Deheng's life, and to prevent Deheng's things from being taken away by spies of other forces, you must be cautious. There can be no negligence. Yuan Chang made a straight face and said in a rare stern tone.

It's not that Yuan Chang is too careful. It's that he had to.

In the history of China, there were five classes: scholars, farmers, industrialists, merchants, and martial arts. The status of a warrior is similar to that of a merchant, except during the war years, the status of a warrior may not be as good as that of a merchant. And Ma Jun, as an inventor, can barely be regarded as a worker in the five classes. The so-called "worker" refers to the craftsman in the manufacturing industry, but there is also a difference between the craftsman. For example, if he makes tools that benefit the people, such as hoes, shovels, etc., such craftsmen can be called workers; There is also a kind of inventor who makes what is called a strange and ingenious thing, and is not regarded as a worker, but as a pariah, who is not in the five classes, and is on the same level as the slave, such an inventor is not even a merchant or a warrior.

And Ma Jun is an inventor, Xun watch is from the Xun family. Tian Kai is also a general, and it is reasonable if he does not pay attention to Ma Jun. Therefore, Yuan Chang naturally wanted to raise this point so harshly.

In feudal times, except for a few very famous craftsmen. Most of the craftsmen were treated as slaves, and they were given away. For example, Li Shimin in the Tang Dynasty, Tubo came to ask for marriage. Li Shimin very generously sent a large number of craftsmen to Tibet, and the result. Relying on these craftsmen, the Tibetans strengthened the equipment of their soldiers. The Tang Dynasty perished, and Tubo was still alive and well, and it was not destroyed until the Song Dynasty. This shows the contempt of the ruling class for the class of workers in the feudal era.

In fact, just as Yuan Chang thought, Xun Biao and Tian Kai didn't attach much importance to Ma Jun before, in their opinion, Ma Jun is just a craftsman, where can he spend too much thought. However, at this moment, Yuan often used a rare stern tone, so he couldn't afford them not to pay attention to it, and re-examine the craftsman in front of him who was not amazing.

Seeing their expressions, they obviously took their words to heart, and Yuan Chang was much more relieved.

After explaining again, Yuan Chang asked a few people to do their own business, and in the hall, there were only three people, Yuan Chang, Guo Jia and Dian Wei. I saw that the three of them all showed a sinister smile, obviously, someone was going to be calculated by Yuan Chang again, as for who was so unlucky to be calculated, it was unknown.

"Fengxiao, now that I am no longer in Beijing City, those big families who want to come to Beijing City should also start to move!" Yuan Chang's right hand tapped the desk for a while, and said in a low voice.

"What the lord said is true!"

Guo Jia nodded, and said in the same deep voice: "According to the report from the spies in Beijing, the four big families of Wang, Li, Lu, and Tang are the most frequent, while the rest of the small and medium-sized families seem to be still waiting. Among them, the Lu family in Beijing and the Lu family in Fanyang County resisted the most obviously. The Taishou of Fanyang County is a child of the Lu family, and the work of measuring the land is also extremely uncooperative, and the officials who went to the Lu family to measure the land were also beaten out by the Lu family. According to the news heard by the spies, the Lu family had sent people to Jizhou to find Lu Zhi to discuss countermeasures, apparently strongly opposing the reform of the lord. ”

Regarding the situation that Guo Jia said, Yuan Chang had already expected it. It is also a pity that the Youzhou Shi clan is not very dense, if it is in Guanzhong, Jingzhou and other places, I am afraid that those Shi clan will have already rebelled in groups, and they will not act as cautiously as now. The four major families in Beijing, Wang, Li, Lu, and Tang, are just one big family in one county, and from the whole world, these four families are nothing at all. The only deep-rooted scholar family in Youzhou is only the Lu family of Fanyang County.

The Lu clan of Fanyang has existed since the Spring and Autumn Period and the Warring States Period, Tian and Dai Qi, Lu and Gao Er clans were driven out, and after leaving Luyi in Changqing County, Shandong Province, they scattered between Yan and Qin, and the main branch was concentrated in Fanyang. When Fan Yang Lu was in Qin Shi Huang, there were the famous Doctor of the Five Classics Lu Xi and Doctor of Astronomy Lu Sheng. In the early days of the Western Han Dynasty, there was Lu Xuan, the king of Yan, and now he is known as "the model of scholars, the Zhen Han of the country", and the great Confucian Lu Zhi of Confucianism in the sea, all of whom came from the Fanyang Lu family. And when it came to the Wei, Jin, Southern and Northern Dynasties to the Sui Dynasty, Lu Zhi, Lu Chen, Lu Yan, Lu Miao, Lu Xuan, etc., the descendants of Lu Zhi, were all official eunuchs and scholars. From Lu Xuan to his great-grandson, there are 100 people in a family, living together with common wealth, and there are 18 people who are famous as officials and are recorded in history. The son of the imperial family wants to find the Lu family to marry, and the history is known as "Fanyang Lu family, one family and three princesses." "The imperial family also wants to accept the daughter of the Fan Yang Lu clan as a noble concubine. The historian has the surname Cui Lu Wang Xie Zhi said: "Looking out of Fanyang, the crown family of Beizhou". In the Tang Dynasty, it was particularly prominent, not only champions, jinshi, emperors, but also talents, including Lu Zhaolin of the "Eight Phases of the Tang Dynasty" and "Four Masters of the Early Tang Dynasty", and Lu Bian of the "Ten Talents of the Great Calendar" and so on. From the end of the Han Dynasty to the Tang Dynasty for more than 600 years, there are more than 840 historical celebrities of the Lu family recorded in the official history. It can be seen that the foundation of Fanyang Lu's family is deep, of course, now Fanyang Lu's family can only become big because of Lu Zhi, Lu Zhi's descendants have not grown up, as long as Lu Zhi's problem is solved, then Fanyang Lu's family will not have a problem, Fanyang Lu's problem is solved, then the problem of the entire Youzhou will naturally be solved.

The key is to deal with Lu Zhi's problem, Yuan Chang is a little hesitant.

To be honest, Yuan Chang still admires Lu Zhi a little. Lu Zhi is known as a politician, military strategist, economist, educator and writer in the cultural circles, and is the precedent of Fanyang Lu's culture, and is respected as the ancestor of Lu's Zhongxing and the ancestor of Fanyang Lu, and is one of the 28 great Confucians who deserve to enjoy the Confucian Temple in history. In addition, Lu Zhi is also a general who can lead troops into battle. At the time of the Yellow Turban Uprising, Lu Zhi was appointed as the commander of the crusade against the Yellow Turbans, but later because of some slander, Lu Zhi was arrested for the crime. After that, Dong Zhuo entered Beijing and controlled the government. Dong Zhuo wanted to depose the young emperor Liu Wei and support Liu Xie, the king of Chenliu, as the emperor, so he summoned hundreds of civil and military officials to discuss, no one dared to speak at that time, only Lu Zhi came out alone to oppose it, Dong Zhuo was furious and ordered Lu Zhi to be executed, Cai Yong interceded for him, and the speaker Peng Bo also hurriedly came out to dissuade Dong Zhuo and said: "Lu Shangshu is a great Confucian in the sea, the hope of scholars! If you kill him now, everyone in the world will be shocked and disappointed." Dong Zhuo gave up and only dismissed Lu Zhi. Dong Zhuo was such a murderous person, but he didn't dare to forcibly kill Lu Zhi, which shows the depth of Lu Zhi's fame.

And Yuan Chang just wants to reform and change the law, and he still doesn't want to use force to solve the problem for a figure like Lu Zhi. Once Lu Zhi is moved, it may cause dissatisfaction among other Confucians, and the relationship between Lu Zhi and his quasi-father-in-law Cai Yong is also extremely friendly, maybe Cai Yong will find him at that time. Therefore, Yuan Chang is naturally difficult to decide.

For the sake of the great cause of the lord's reform and for the sake of all the people in the world, if Lu Zhi can't understand the lord's thoughts, the lord can't be soft-hearted. ”

Guo Jia saw Yuan Chang's expression and knew that Yuan Chang was a little hesitant, so he hurriedly advised. Although Guo Jia is a literati, he is ruthless when he should be, and there will never be the slightest softness. For example, Sima Yi, Zhuge Liang and others, don't look at the faces of ordinary people who are kind literati, let's just say that Zhuge Liang's means of burning rattan armor soldiers, although it is because of the war, it is not difficult to see that these top strategists have a resolute personality that is different from ordinary people.

Hearing Guo Jia's persuasion, Yuan Chang frowned, and a fierce struggle was going on in his mind. After a long time, Yuan Chang's brows stretched, and he seemed to have made a decision in his heart. (To be continued.) )
